Chemical Resistance in Tiles: Everything You Need to Know
Tiles should do more than look good. They must retain their appearance and performance in the presence of water, stains, cleaning agents, food, and chemicals from daily use. It is at this point that chemical resistance in tiles becomes a significant quality parameter.
Whether you’ re choosing tiles for a residential, hospitality, healthcare, retail, or high-traffic area commercial project, knowledge of tile chemical resistance can assist you in making a better choice.
A tile can look ‘premium’ when first laid, but the true test of its performance comes with time. The appropriate degree of chemical resistance enables a tile surface to be exposed to widely-used substances without experiencing unwanted wear.
What Is Chemical Resistance in Tiles?
Chemical resistance in tiles is defined as the ability of a ceramic or porcelain tile surface to resist permanent damage when it comes into contact with certain chemicals.
Common chemicals found in household cleaning products, acids, alkalis, and other chemicals found in various environments.
Chemical resistance is more than just whether a tile can endure an accidental spill. It is a performance attribute that is assessed using standardized tests. ISO 10545-13:2016 defines a test method for the determination of the chemical resistance of ceramic tiles at room temperature.
Various test solutions of household chemicals, swimming-pool salts, acids and alkalis are included in the standard.
Why Does Tile Chemical Resistance Matter?
Tiles are often subjected to materials that can alter their surface. In kitchens, food ingredients, oils and cleaning products may be present, while bathrooms are constantly treated to detergents and cleaning agents.
Commercial and industrial style environments can be subjected to even higher levels of chemicals.
Proper tile chemical resistance can help maintain the original appearance of the surface and prevent chemical-induced damage.
Chemical resistance is thus an important tile property to consider for architects, interior designers, contractors, and homeowners, along with other tile properties such as water absorption, breaking strength, stain resistance, surface finish and intended use.
You are not just trying to pick a pretty tile, you are trying to pick a tile whose performance is appropriate to the environment.
Which Chemicals Can Affect Tiles?
Different types of environments will have different things that the tiles are exposed to. Household chemicals, acids, alkalis and cleaning agents are common.
Household Chemicals
Common household products can be spilled on kitchen, bathroom and floor tiles. These can be detergents, disinfectants and other cleaning solutions.
This makes chemical resistance an everyday concern, particularly in places that need constant cleaning.
Acids
Acidic materials may be more aggressive against some tile surfaces and finishes. The effect depends on the tile and the chemical, concentration, exposure conditions and other factors.
In any place where an acid might be, it is a good idea to consult the Manufacture's chemical resistance data.
Alkalis
Alkaline compounds also play a significant role. Strong alkaline cleaning agent may have different behaviour compared with the daily use neutral cleaning agent.
The appropriate tile should be chosen based on anticipated chemical exposure rather than assuming each tile will do the same thing.
Swimming Pool Chemicals
Swimming pools and wet recreational areas can subject tile surfaces to chemicals and salts. Thus, chemical resistance is an important factor for the application of the same in these environments.
How Is Chemical Resistance Tested?
A resistance to chemicals for tiles is a method to determine the reaction of a tile to certain chemical solutions at a certain concentration under specified conditions.
ISO 10545-13:2016 defines a single test method for among others ceramic tiles. The procedure includes test solutions and assessment of tile after chemical contact.
This is an important distinction because you can’t assess chemical resistance just by looking at a tile or by assuming that a certain tile material is inherently resistant to all chemicals.
Ask for technical documentation or testing information when chemical resistance has significance to the project in product comparisons.
Ceramic Tile vs Porcelain Tile: Does Chemical Resistance Differ?
Ceramic and porcelain tiles can both perform well, but the chemical resistance of ceramic tile and the chemical resistance of porcelain tile are dependent on the individual product and not just the material name.
Performance can be affected by the tile body, glaze, surface finish, manufacturing method, and end use.
Porcelain tiles are often characterized by their dense body and low water absorption, however not all porcelain tiles have the same chemical resistance.
Similarly, ceramic tiles may have various surface properties depending on their composition and finish.
The safest bet is always to examine the technical data sheet of the specific tile in question.
Where Is Chemical Resistance Especially Important?
Resistance to chemicals is especially important in areas where tiles are subject to regular cleaning or contact with substances that could be corrosive.
Kitchens
Food residues, oils, detergents and cleaning agents can all be found on kitchen surfaces. Chemically resistant tiles can be a good choice when easy cleaning and long-term surface performance are required.
Bathrooms
Cleaning products, soaps and disinfectants are constantly in use in bathrooms. Choosing tiles with the right chemical resistance can also help in making cleaning easier in the long term.
Commercial Spaces
Retail stores, hospitality environments, offices and other commercial spaces may require frequent cleaning. Here, tile durability and chemical resistance are more important because the surface may be cleaned over and over again.
High-Use Areas
All environments where cleaning is frequent or where there may be exposure to chemicals should be assessed for their own needs rather than deciding on any tile on the basis of color, size or look.
Chemical Resistance Is Not the Same as Stain Resistance
These two aspects have to do with tile performance, but are not the same.
Chemical resistance describes how the tile behaves when subjected to certain chemical agents.
Stain resistance is quantified by the tile's ability to prevent the tile surface from being stained by potential staining agents, leaving a visible mark on the surface.
A tile, then, can perform in four different ways on four different tests.
When you are assessing chemicals resistance and staining resistance, consider the water absorption, surface features and any other applicable technical information for a full consideration.
How to Choose Chemical Resistant Tiles
Prior to choosing tiles, get a sense of the space where they will be placed.
Think about what chemicals the surface might be exposed to, how often the area needs to be cleaned, and whether you might need to use more potent cleaning solutions.
Consult the manufacturer’s technical data. Seek out documented testing, as opposed to generic claims such as “durable” or “easy to clean.”
The full system installation is important to consider. Tile joints, grout and cleaning routines may affect the long-term maintenance performance of a tiled surface.
For demanding applications, consult with the tile supplier, architect, or technical professional regarding anticipated chemical exposure prior to final selection.
Tips for Maintaining Tile Surfaces
Well-maintained tile can last a long time. Always use tile and grout-safe detergents for daily cleaning.
Do not assume that more chemicals are always better for cleaning. Follow tile manufacturer's cleaning instructions in particular for special finishes.
Routine maintenance Neutral cleaners are typically a safe bet and can be used for both tile and grout, while stronger cleaners may be needed in some heavy-duty situations, according to the product. When in doubt, consult instructions from the product manufacturer regarding cleaning, and test unknown cleaning products on a hidden area if applicable.
Final Thoughts
Chemical resistance in tiles is an important factor in tile selection but is often not considered. A pretty surface should also be able to function as required by the environment.
In kitchens, bathrooms, commercial and high-use spaces, knowledge of tile resistance to chemicals guides architects, designers, contractors and homeowners in better material decisions.
For your next tile selection, think beyond color and style. Think technical performance, end-use, maintenance needs and confirmed product specifications.
The proper tile is not just how it looks on day one, but how reliably it stands up to the test of time.
